Those of you who have played with a Pleo know exactly where this is going. The Pleo averages about 30 minues per 2-3 hour charge. Just swap batteries you say? Nope, the battery packs aren’t available. Fortunately, you can make your own pretty easily. The basic frame is a standard battery pack for 6 AA’s. There are only a few modifications necessary to line up the leads and make it fit once you’ve loaded it with batteries.
